What's New in M91
1.4.2
September 17, 2026
M91 is now built around channels. A channel is a group of people who get alerted together. Create one, invite people by phone number, and you get a link that alerts everyone in it. No account setup, no API keys, no integration work — paste the link anywhere that can call a URL. • Sign in with your phone number. Nothing else to set up. • Create a channel for anything you need watched, and invite the people who should be woken. • Each channel has its own alert link. Open it in a browser, put it in a cron job, a monitoring tool, or a spreadsheet — anything with a "URL to call" field. • Give someone else permission to send. They're invited, they accept, and they get their own link. • Send a test alert with one tap and watch your phone ring before you wire anything up. Fixes • Alerts sent without response options now play the M91 alert sound instead of the default notification sound. • Tapping an alert notification now opens the alert, including when the app was closed or in the background. • You no longer get an escalation phone call for an alert your phone already received. • Channel names, member counts and the send controls no longer flicker while a channel loads. • Searching no longer leaves you on a screen with no way to clear it.
